Found the article at the Malaysian Insider, about how that the pings were not from the Black Box....
Well thus makes sense and a full u-turn on the search case again
" A few months ago, a colleague at the University of Hong Kong mentioned that a great white shark had been tracked all the way
from South Africa to Australia. This came to mind on April 5 when the first ping was detected in the search for Malaysia Airlines
flight MH370 and thought to have come from the airplanes black boxes."
" pinger transmitters attached to all sorts of marine life from whales to sharks, sea turtles, tuna, seals, swordfish, etc. "
" To cite just one example, the real-time tracking of more than 400 marine animals is listed at
www.seaturtle.org/tracking.
"
For several decades, pingers with frequencies of 30 to 50kHz have been commonly used to track large, deep ocean animals.
"
Location and other data is transmitted to receivers in the ocean or to satellites whenever the animal surfaces. Acoustic pingers
are also widely used as fishing net protectors"...
"One wonders if, in the eagerness to believe and the absence of any other lead, the authorities directing the search have ignored or downplayed
evidence that is clearly contrary."

MSM article by Bloomberg.com published Apr 9, 2014:
"Aircraft black-box pingers, like those from the missing Malaysian jetliner lying somewhere in the depths of the Indian Ocean, emit a sound
signature
almost impossible to mimic in nature.
Their standard frequency of 37.5 kilohertz, outside the range of human hearing, and once-a-second tempo were chosen in part to minimize chances
the signals could be mistaken for a marine mammal or another manmade object."

Old MSM CNN Article published April 7, 2014:
"The Chinese Haixun 01 patrol ship
detected pulses at a frequency of 37.5 kHz, the Chinese state-run Xinhua news agency reported.
That's the
same frequency of black box pingers -- and that frequency is no accident."
"The Haixun 01 reported two pulses within 2 kilometers (1.25 miles) of each other."
"The British ship HMS Echo recorded one event that was determined to be unfounded. The Ocean Shield, an Australian naval vessel equipped
with sophisticated listening equipment, has also detected "an acoustic noise" in another area of the ocean to the north.
According to a CNN calculation, the Australian ship was about 350 miles (565 kilometers) away from the spot where the Chinese ship detected
the pulses. It's also unclear whether the sound the Australian ship detected was related to Flight 370."
"The Chinese said they did not have time to record the pulses, precluding a scientific analysis of the sounds."
"In video of the Haixun 01, it appears the Chinese had a spare pinger in the boat.
Anish Patel, president of pinger manufacturer Dukane Seacom, says it is not recommended to have a pinger near the area where you are trying to listen."
"The hydrophone the Chinese used to detect the pulse is "designed for shallow water applications," not for the deep water, said Thomas Altshuler of
Teledyne Marine Systems, manufacturer of the hydrophone."

More info links about Pingers/Pinger use on Marine mammals:
[ame="http://en.wikipedia.org/wiki/Military_dolphin"]Military dolphin - Wikipedia, the free encyclopedia[/ame]
"A military dolphin is a dolphin trained for military uses. The United States and Soviet militaries have trained and employed oceanic
dolphins for several reasons. Such military dolphins have been trained to rescue lost naval swimmers or to locate underwater mines."
"The dolphins and sea lions are trained by five teams of the Navy's Marine Mammal fleet members. One team specializes in swimmer
detection, three teams in mine location, and another team in object recoveries. "
[ame="http://en.wikipedia.org/wiki/United_States_Navy_Marine_Mammal_Program"]United States Navy Marine Mammal Program - Wikipedia, the free encyclopedia[/ame]
"MMP animal teams have been deployed for use in combat zones, such as during the Vietnam War and the Iraq War.
The program has been dogged by controversy over the treatment of the animals and speculation as to the nature of its mission and training."
"NMMP dolphins, such as the one pictured here
wearing a locating pinger, performed mine clearance work in the Persian Gulf during the Iraq War."
http://www.nrdc.org/wildlife/marine/sonar.asp
"Whales and other marine mammals rely on their hearing for life's most basic functions, such as orientation and communication. Sound is how they find food,
find friends, find a mate, and find their way through the world every day."
"Manmade sound waves can drown out the noises that marine mammals rely on for their very survival, causing serious injury and even death."
"The Navys most widely used sonar systems operate in the
mid-frequency range. Evidence of the danger caused by these systems surfaced dramatically in 2000, when
whales of four different species stranded themselves on beaches in the Bahamas. Although the Navy initially denied responsibility, the government's investigation
established that mid-frequency sonar caused the strandings."
Article by Los Angeles Times:
"The bright orange pingers look like oversize hot dogs. They are 6 1/2 inches tall and emit an annoying beep that travels
at least 300 feet in water."

NOAA National Oceanic And Atmospheric Administration article:
"Pingers are small acoustic devices Northeastern fishermen are required to attach to their gillnets to reduce marine mammal
bycatch during specific fishing seasons. When a gillnet is submerged underwater, the pingers attached to the net broadcast short, high pitched sounds
or pings every four seconds. Those pings are designed to deter harbor porpoises from getting close to the net."

"We collaborate with scientists and researchers in Governments and Universities, helping develop the scientific credibility of using Pingers. "
"Although the use of Pingers is mandated by law in the USA and in Europe, there are many regions around the world that lack the scientific
understanding of Pingers and how and why they reduce marine mammal entanglements in fishing gear."

Whale Pinger:
"
Whale Pingers operate with a 3 kHz (+/- .5 kHz) frequency at 135 dB (+/- 4 dB). Since fitting Future Oceans Whale Pingers to shark nets in Australia in 2010.."
Dolphin Pingers:
"
Dolphin Pinger emits a 145 decibel signal, every 4 seconds for 300 m/s."
"
The 70 kHz Dolphin Pinger works by emitting a signal that is known to be in the best hearing range of most Dolphin species."
Porpose Pinger:
"
Porpoise Pinger of 10 kHz at 132 decibels, emission interval every 4 seconds for 300 m/s are specified in the USA under the National Marine Fisheries Service..."
